摘要: Phenacyl esters of fatty acids have been formed In an es-sentially quantitative manner using crown ethers as catalysts. These esters absorb UV radiation strongly at 254 nm, allowing the detection of as small a quantity as 1 ng of C2 acid, and 50 ng of C20 acid. The method of synthesis is in-expensive and can be carried out in virtually any aprotic solvent system in a short period of time. Reaction conditions do not require total exclusion of water, thus simplifying the procedure. Liquid chromatographic separations of these es-ters have been …
